Driver Wiper Arm

         Should you notice that your drivers wiper blade seems to lift off the windshield the last of the swipe, then you need to adjust the wiper arm, not the wiper blade. Run your wipers and shut off the ignition so the arm stops as shown in the picture. Take a 13 mm wrench or socket and tighten the arm, then take your hand and shove down rather hard a few times right where the yellow arrow is pointing. Don't drive it through the window but you'll feel the aluminum arm bend. This will save you from buying a new arm as well as destroying wiper blades that are not the problem.
